본 연구는 SWAT (Soil and Water Assessment Tool)을 이용하여 섬진강유역 주암댐에서 영산강유역(3,371.4 km2)으로의 유역간 물이동량조절에 따른 영산강의 하천유량 및 수질변동을 분석하였다. 이를 위해, SWAT의 Inlet 기능을 이용한 물이동과 영산강유역 하수처리장들의 방류량 자료를 고려한 SWAT을 구축하여, 마륵(MR) 수위관측소와 다기능보 2개(승촌보;SCW, 죽산보;JSW) 그리고 3개의 수질관측소(광주;GJ2, 나주;NJ, 함평;HP)를 대상으로 총 14년(2005~2018) 동안의 유량과 수질을 검보정하였다. 3개 지점 하천유량의 검보정 결과, R2, NSE, RMSE, PBIAS는 각각 0.69 ~ 0.81, 0.61 ~ 0.70, 1.34 ~ 2.60 mm/day, -8.3% ~ +7.6%였으며, 수질은 SS, T-N 및 T-P 각각 R2가 각각 0.69 ~ 0.81, 0.61 ~ 0.70, 0.54 ~ 0.63의 범위를 보였다. 물이동량을 고려한 영산강유역의 하천유량은 평균 12.0 m3/sec로 나타났으며, SS, T-N 및 T-P의 평균 농도는 각각 110.5 mg/L, 4.4 mg/L, 0.18 mg/L 이었다. 물이동량의 변화에 따른 영산강의 유량과 수질의 변화를 보기 위하여, 물이동량의 증가(110%, 130%, 150%)와 감소(90%, 70%, 50%)를 적용하였다. 대표적으로 증가시나리오 130%의 경우, 하천유량과 SS의 농도는 각각 12.94 m3/sec (+7.8%), 111.26 mg/L (+0.7%) 증가, T-N과 T-P 농도는 각각 4.17 mg/L (-5.2%), 0.165 mg/L (-8.3%)로 감소하였다. 반면 감소시나리오 70%를 적용하였을 때, 하천유량과 SS의 농도는 각각 11.07 m3/sec (-7.8%), 109.74 mg/L (-0.7%)로 감소, T-N과 T-P 농도는 각각 4.68 mg/L (+6.4%), 0.199 mg/L (+10.6%) 증가하였다.

This study is to evaluate stream flow and water quality changes of Yeongsan river basin (3,371.4 km2) by inter-basin water transfer (IBWT) from Juam dam of Seomjin river basin using SWAT (Soil and Water Assessment Tool). The SWAT was established using inlet function for IBWT between donor and receiving basins. The SWAT was calibrated and validated with 14 years (2005 ~ 2018) data of 1 stream (MR) and 2 multi-functional weir (SCW, JSW) water level gauging stations, and 3 water quality stations (GJ2, NJ, and HP) including data of IBWT and effluent from wastewater treatment plants of Yeongsan river basin. For streamflow and weir inflows (MR, SCW, and JSW), the coefficient of determination (R2), Nash-Sutcliffe efficiency (NSE), root mean square error (RMSE), and percent bias (PBIAS) were 0.69 ~ 0.81, 0.61 ~ 0.70, 1.34 ~ 2.60 mm/day, and -8.3% ~ +7.6% respectively. In case of water quality, the R2 of SS, T-N, and T-P were 0.69 ~ 0.81, 0.61 ~ 0.70, and 0.54 ~ 0.63 respectively. The Yeongsan river basin average streamflow was 12.0 m3/sec and the average SS, T-N, and T-P were 110.5 mg/L, 4.4 mg/L, 0.18 mg/L respectively. Under the 130% scenario of IBWT amount, the streamflow, SS increased to 12.94 m3/sec (+7.8%), 111.26 mg/L (+0.7%) and the T-N, T-P decreased to 4.17 mg/L (-5.2%), 0.165 mg/L (-8.3%) respectively. Under the 70% scenario of IBWT amount, the streamflow, SS decreased to 11.07 m3/sec (-7.8%), 109.74 mg/L (-0.7%) and the T-N, T-P increased to 4.68 mg/L (+6.4%), 0.199 mg/L (+10.6%) respectively.
